80 Lower Jig

An 80 Lower Jig is the best way for an AR 15 builder to complete their 80 percent lower receiver. Since, by design, an 80 percent lower still requires the builder to complete the last 20% of the milling process to complete the lower receiver, an 80 lower jig is mandatory for the completion of an 80 percent lower. The 80 Lower Jig allows you to mill out the remaining 20%, the fire control group, while serving as the milling guide with built-in safeguards to protect against user error.

80 Lower Jigs are constructed with aerospace grade aluminum alloy so they can be reused to complete several 80 percent lowers. Our store carries both AR15 Jig and AR 10 Jigs for your convenience. They are designed with safeguards in place so that you do not drill too deep or mill out more than necessary.

While the actual milling process takes some skill and attention-to-detail, it is a fairly straightforward process and all our 80 Lower Jigs come complete with easy step-by-step instructions. Also, the individual components of the 80 lower jigs are clearly labeled and coordinate with the step-by-step instructions to ensure your AR-15 build is a strong and sound success!
